We investigated the ultrastructure of Birbeck granules which are found in some malignant histiocytoses such as histiocytosis X, Letterer-Siwe disease, Hand-Schüller-Christian disease, eosinophilic granuloma of the bone and self-healing reticulohistiocytosis. The research is based on the systemic study of Birbeck granules, from their formation to intracytoplasmic development, examining with the electron microscope at regular intervals ultrathin sections derived from biopsies of two cases of Langerhans cell histiocytosis.

UI MeSH Term Description Entries
D007801 Langerhans Cells Recirculating, dendritic, antigen-presenting cells containing characteristic racket-shaped granules (Birbeck granules). They are found principally in the stratum spinosum of the EPIDERMIS and are rich in Class II MAJOR HISTOCOMPATIBILITY COMPLEX molecules. Langerhans cells were the first dendritic cell to be described and have been a model of study for other dendritic cells (DCs), especially other migrating DCs such as dermal DCs and INTERSTITIAL DENDRITIC CELLS.

D006646 Histiocytosis, Langerhans-Cell A group of disorders resulting from the abnormal proliferation of and tissue infiltration by LANGERHANS CELLS which can be detected by their characteristic Birbeck granules (X bodies), or by monoclonal antibody staining for their surface CD1 ANTIGENS. Langerhans-cell granulomatosis can involve a single organ, or can be a systemic disorder.
